How to Determine Your Ring Size

Finding the right ring size is essential to ensure a comfortable fit and enhance your jewelry experience. Follow these simple steps to determine your ring size at home:

Using the Paper Strip and Ruler Method:

  1. Wrap the Paper Strip: Gently wrap a paper strip around the base of your finger where you want the ring to sit.
  2. Mark the Intersection: Use a pen or pencil to mark the point where the paper strip overlaps itself.
  3. Measure the Length: Carefully measure the length of the paper strip in millimeters using a ruler.
  4. Select the Closest Size: Refer to our ring size chart and choose a ring size that matches the measurement you obtained.
  5. You can also measure the inner diameter of the ring you normally wear and get a number that you can use to find your length in the "NTERNAL DIAMETER (MM)" column of the table below and choose the corresponding size.

Additional Tips to Keep in Mind:

  • Your ring should fit snugly, ensuring it doesn’t slip off but can slide over your knuckle with ease.
  • If your knuckle is larger than the base of your finger, measure both areas and choose a size in between.
  • Measure your ring size in the evening when your fingers are warm, as finger size may fluctuate with time and temperature. Note that the dominant hand's fingers tend to be thicker.
  • It’s always best to measure multiple times to ensure accuracy.
